I don't blame you at all for feeling this way. She took advantage of you, used you, etc. Sorry you have to deal with this crap, but don't sign that paper at all. I know you said you won't, which is good, but considering all the lies in it, don't even touch it. Sounds like she is a controlling person, and she probably figures she can continue to do that regardless, but thankfully you aren't letting that happen, good for you!
